Seed and Chemical Meter Chains
Lubricate all chains at intervals to maintain freedom at every
chain link joint. Use a multipurpose spray lubricant on
chains, because it penetrates into the rollers on the chain.
Spray chains if planter is going to be idle to prevent the
chains from rusting and becoming stiff. Stiff chains will cause
metering inaccuracies.
Type of Lubrication: Multipurpose Spray Lube
